Cochlear Implantation in Pediatric Patients: Comparison of Limited-Incision and Standard Cochlear Implantation

“…Using ST for CI can cause multiple complications, such as tissue devascularization, postoperative edema, and increased risk of infection and tissue necrosis [7,8]. Nowadays, some techniques, such as LIT, involving small incisions have been developed in order to disrupt a lesser amount of the soft tissue blood supply, decrease the amount of created dead space [8,9], and reduce the operative time [7][8][9][10].…”

“…Nowadays, some techniques, such as LIT, involving small incisions have been developed in order to disrupt a lesser amount of the soft tissue blood supply, decrease the amount of created dead space [8,9], and reduce the operative time [7][8][9][10].…”

“…In the same line, Stratigouleas et al [8] mentioned the advantages of LIT to be less dissection and postoperative edema, less venous stasis, decreased risk of pressure necrosis on the skin, and earlier mapping times (typically occurring on postoperative day) compared to ST. Likewise, Mann and Gosepath [21] used the similar technique and reported no postoperative complications.…”

“…These large manipulations could in turn lead to postoperative complications, such as devascularization, that resulted in hematoma and seroma formation as well as flap necrosis and infection [4][5][6]. The limited-incision technique (LIT), on the other hand, involves smaller incisions and tissue flaps, including no well or tie-down sutures at all [7][8][9][10][11]. This CI technique involves small soft tissue flaps and a tight subperiosteal pocket for the device.…”

Time of cochlear implant surgery in academic settings

“…A study published in 2000 reported operative time of 192-206 minutes and total anesthesia time of 249-269 minutes for unilateral CI. 3 An accurate estimation of the length of time required to perform CI would be valuable for costbenefit analysis, determining appropriate 3 rd party reimbursement, and determining if newer, less invasive techniques for CI, such as endaural, 4 suprameatal, 5,6 minimal access, [7][8][9][10] or percutaneous 11 approaches will provide a tangible benefit in terms of decreased operative time. Shorter surgical times translate into decreased duration of general anesthesia and decreased fees, critical factors in determining the overall cost-benefit analysis for a given procedure.…”
